A cellular base station serves a multiplicity of single-antenna terminals over the same time-
frequency interval. Time-division duplex operation combined with reverse-link pilots enables …

With solid theoretical foundations and numerous potential applications, Blind Signal
Processing (BSP) is one of the hottest emerging areas in Signal Processing. This volume …

The demand for wireless mobile communications services is growing at an explosive rate,
with the anticipation that communication to a mobile device anywhere on the globe at all …

Space-time processing can improve network capacity, coverage, and quality by reducing co-
channel interference (CCI) while enhancing diversity and array gain. This article focuses …

Beamforming for transmission in a network is, in several aspects, more difficult than
beamforming for reception. At first sight, the problems appear to be equivalent; because the …

Joint power control and beamforming schemes are proposed for cellular systems where
adaptive arrays are used only at base stations. In the uplink, mobile power and receiver …

This article reviews space-time modem technology for mobile radio applications. We begin
with motivations for the use of space-time modems and then briefly discuss the challenges …

In this paper, the problem of pilot beam pattern design for channel estimation in massive
multiple-input multiple-output systems with a large number of transmit antennas at the base …

This paper addresses the problem of uplink (UL) and downlink (DL) channel estimation in
frequency-division duplexing (FDD) massive multiple-input multiple-output (MIMO) systems …

The effect of spatial diversity on the throughput and reliability of wireless networks is
examined. Spatial diversity is realized through multiple independently fading …
